I need PDP-11/34A Help Again (Suprise Suprise)

by Andreas.Freiherr＠Vishay.com

Owen, still interested in getting your PDP-11/34 to work? - I am just about to reassemble mine after relocation. RUN light off and display 000002 means the processor halted at memory location 2, so it has probably executed a HALT instruction (opcode 000000) from location 0. Try this: while holding the CNTRL button, press BOOT. This should launch the program from your ROM. Depending on which type you have (look for modules labeled M9301 or M9312 in slot 3 or 4, whatever is next to the processor), your milage may vary here. The console terminal should print four numbers in octal, followed by an "@" or a "$" as a prompt in a new line ("Dave, my mind is going..."). Depending on the ROM, you may need to enter either 773000G (standard start address and GO command, pressing the return key is _not_ required here) or a two-letter device code to boot. The bootstrap module may also be wired to boot from a predetermined device without asking. BTW: The DL11-W has 20mA drivers as well as RS-232. (Note the "1488" and "1489" chips being present as well as a number of transistors and other discrete components.) Which set is used depends on the cable: the plug will have some wire connections to code it for either 20mA current loop or RS-232 / V.24. If you have the original cable with the usual DB-25 connector, it should be OK: current loop used a completely different 6-pin "Mate-n-Lock" connector. For the settings at the terminal, I don't know your particular type, but with most DEC lines you should be best prepared if you use XON/XOFF handshake (for "Main Rcv Hndsk" / "Main Xmt Hdsk"). Since at PDP-11 times, the 8th bit was commonly used as a parity bit, set your terminal to ignore this. Otherwise, you may get garbage characters instead of about every second readable character. We may get this straight later, when we know what operating system you have. A RS-232 break signal can sometimes cause a PDP-11 to HALT (depending on settings on the DL11-W board), so you may want to avoid this... (perhaps by choosing an appropriate setting for the "Disconnect" option for now?) So much from memory. If you need more details, let me know, and I'll dig into the docs.

OT: Pricing (was RE: Microdata "Microprogramming Handbook")

by Robert_Feldman＠jdedwards.com

I've done price searches on the 'net for things I want to buy (an airbrush and a portable SW radio, in particular), and found prices ranging from about 50% MSRP to 125% MSRP. Wherever you go, it's still buyer beware (and be aware).

More DELLness & TRON! :D

by bpope＠wordstock.com

Y'all, I am sure you will all be happy to know the following... Dell fields Super Bowl deal Dell Computer announced that it has signed on to be the National Football League's official computer systems provider for the upcoming Super Bowl XXXVI. Dell also signed a deal to be the NFL's hardware supplier for the remainder of 2002. As part of the Super Bowl agreement, the company will provide on-site service and support for computer systems used in Super Bowl operations, which will include some 200 Dell desktops imported to New Orleans from league headquarters. And under the new Dell-NFL hardware agreement, the league will purchase 120 or more PowerEdge 2500 servers and a storage area network. Dell says it has had a sales relationship with the NFL since 1998. --John G. Spooner, ZDNet News And.... TRON Collectors Edition on DVD was released today!! :-D The coolest computer animation of the 80's! Cheers, Bryan Pope

NCD 88k xterm info anyone?

by claudew＠videotron.ca

Hello from mild and almost snowless Montreal... A recent find for $5. NCD 88k xterm, no keyboard, no ram, no monitor... Very little help on the web about this. I wanna try this out, I am not sure why... Anyways who knows the ram simms specs and where they go in this thing (unit came with no ram) I managed to get some "normal reaction" by putting a 1M simm in the inner most simm socket and 2 X 4M simms in the outter most sockets. I am saying "normal reaction" cause I have still not found a monitor that will produce stable output on this thing. I do see somekinda "unsync-ed" POST and looks like text appearing and scrolling on screen every approx 5 secs, imagine the term is looking to boot from somewhere... Who can tell me more about the video output specs? Looks like mono and my pinout seems ok 15,16,17 R,G,B and 26 TTL Vsync and 18 TTL Hsync from looking at it with a scope... Any help appreciated...

AT&T hardware

by xds_sigma7＠hotmail.com

Pat, Unless you have a need to control a bunch of 3270-emulating terminals, a 6544 isn't a terrible useful thing to have. It's basically a non-IBM version of a 3174, etc., which is a unit used to hook up many terminals to your 3270-protocol host computer, be it mainframe or minicomputer. I don't know what terminals the thing is meant for, since it beats me if AT&T's terminals support 3270, but they probably do, though I'd imagine it doesn't use coax.. Which, if that is true, might limit you to using AT&T terminals with it, which is kinda crappy.. Hope that helps some Will J _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com
